NEW YORK — The Dow Jones Industrial Average opened Wednesday at 54,467.23, extending a remarkable run of record-setting sessions on Wall Street as falling oil prices, strong corporate earnings and growing optimism over a potential resolution to the Strait of Hormuz crisis continued to fuel investor enthusiasm.

The blue-chip index's early Wednesday level built directly on Tuesday's historic close, when the Dow surged 907.47 points, or 1.71%, to finish at 54,085.88, marking the index's first close above the 54,000 threshold in its history. Wednesday's opening level of 54,467.23 represented a further gain of roughly 381 points, or about 0.7%, from that record close, suggesting the rally that has defined trading over the past several sessions was carrying fresh momentum into the new trading day.

Tuesday's session saw all three major U.S. stock benchmarks close at record highs simultaneously. The S&P 500 surged 1.79% to close at 7,736.52, its first record close in two months and a level that surpassed its previous closing peak set in early June. The tech-heavy Nasdaq Composite climbed 2.59% to finish at 26,584.99, powered in part by a 29% rally in Palantir Technologies shares, though the index itself remained roughly 2% below its own record high set in early June as it continued recovering from a summer slump.

The Dow's advance Tuesday marked its second consecutive all-time high, following a close above 53,000 points for just the second time ever on Monday. That back-to-back run of records came as Amazon briefly eclipsed a $3 trillion market........
